Of course there isn't. If there were, it would immediately be redefined as "natural," instead of "supernatural."
This is why I like to say that there is no supernatural, only natural things we do not yet understand.
Personally, I have found it to be very hard to tell what ideas I come up with are reasonable and which are not based on just my own thoughts. They always sound perfectly reasonable when I am only applying my own reason to them. It is whether I can eventually explain them to other people that determines their actual reasonableness. That appears to be the main problem you're having here. Did you discuss these things with other people as you were thinking about them?
